I have previously blogged about the issues that preprints can cause on Google Scholar. Today I was reminded that these issues have real-world implication for junior scientists, and that they may discourage junior scientists from posting preprints.
So your latest scientific masterpiece has come back from review with the most likely outcome other than rejection: major revision. The reviewers and the editor think that your work has merit, but they also have a long list of comments and criticism that they expect you to address before the article is acceptable for publication. You read the reviews and you feel like they lay out two years worth of work. How do you best deal with this situation? Read More
Google Scholar has a serious bug when it comes to preprints. If you have published a preprint of your paper, the later journal publication can be completely invisible to Google Scholar, seemingly absent from their entire database. Even a search for the exact article title will not find the article. And this condition remains for months. (It will eventually fix itself, though. After about a year.) I have now seen this bug in action for several of my papers, and I am confident it’s a reproducible flaw and not a one-off. I reported the issue to the Google Scholar team about a year ago (or at least, I filled in some web form that seemed to be designed to send them feedback) but I have received no response and the bug clearly still exists. I hope that with this blog-post I can draw some attention to this serious issue, so we can have it fixed. Thousands of scientists rely on Google Scholar every day. For many recent articles, this bug will steer these scientists towards outdated, early versions and make the authoritative article versions completely inaccessible.
As part of the recent discussion on anonymous peer review, several people spoke out in favor of double-blind peer review, where neither the authors nor the reviewers know who the others are. I have thought a lot about double-blind peer review, and I’m not entirely convinced, in particular when it comes to grant applications. While double-blind review might solve certain problems and remove certain biases, it would almost certainly amplify other issues, and whether the net effect would be good or bad is unclear. It would also give more power to people such as editors and program managers who operate outside the blinded process. Read More
One of the key challenges in obtaining a PhD is scheduling a committee meeting. In fact, I think that anybody who has managed to successfully schedule three or four committee meetings probably deserves a PhD just for that feat. After all, getting five professors into the same room at the same time is a tall order. Since scheduling committee meetings is such an integral part of graduate education, there should probably be a class on how to do this successfully. However, I don’t think any such class exists. So maybe this blog post can serve as a substitute. Read More
In a recent blog post, Mick Watson argued that anonymous peer review is bad for science. The post makes a number of insightful and valid points. However, the one point I cannot agree with is that junior scientists don’t need anonymity so they can freely speak their mind without fear of retaliation. Mick Watson argues that retaliation should be a non-issue, and that in the cases where it is not we just have to make it so. Frankly, I think this is simplistic black-and-white thinking. There are so many ways in which a senior person can make a junior person’s life more difficult; I would always recommend my graduate students and postdocs that they review anonymously unless they can write a very positive review.

I had a twitter discussion with ggplot2 author Hadley Wickham on whether or not to include a grid background in plots. He thinks the default should have a grid, I think the opposite. I believe we both agree that grids make sense for some plots and not for others, so this is just a question about defaults. On that issue, we remain in disagreement.
This weekend, I finally spent some time learning R Markdown. I had been aware of its existence for a while, but I had never bothered to check it out. What a mistake. R Markdown rocks! It's hands down the easiest and most elegant method to creating rich documents that contain data analysis, figures, mathematical formulas, and text. And it's super easy to learn. I wager that anybody who has RStudio installed can create a useful document in 30 minutes or less. So if you use R, and you've never used R Markdown, give it a try.
A paper published by PLOS Comp. Biol. this month, Chatterjee et al., The Time Scale of Evolutionary Innovation, espouses ideas that are quite similar in spirit to long-standing creationist arguments. I said as much in a few tweets. After having made these comments, I have spent quite some time thinking this paper over. And I simply cannot convince myself that it makes an important contribution to evolutionary biology. It is possible that there’s something I’m missing, but to me the paper looks like a very convoluted and mathematically dense way of making a few tired, trivial, and maybe even tautological arguments.

It seems that Hadley Wickham, the author of the spectacular ggplot2 library for R, is not content with revolutionizing the world of computational data analysis just once. He keeps doing it. This spring, he released the dplyr package, a package that proposes a grammar of data manipulation. I predict that dplyr will become as important for large-scale data analysis and manipulation as ggplot2 has become for visualization. If you like ggplot2, you will love dplyr. Read More
